I went exploring on a little dead-end in the Diablo foothills called Finley Road. According to the map it continues (unpaved) over the south-east shoulder of Diablo and connects up with Morgan Territory Road, but I didn't get that far.

I heard that Happy Hollow was about to close for a year and all the old-style rides and playground equipment was going away, so I went to visit. I also checked out History Park, which is just down the street.
